Here, the magnitude of CD and BC will be cancelled, as they both are in the opposite direction and equal to each other.
the magnitude, towards the diagonal AC will result in CP, which is the direction of the electric field.
magnitude of electric field can be defined as :- The force per charge on the test charge is a straight forward way to define the size of the electric field.

Explanation:
The given data is as follows.
Pulling force on the reel is F = T = 2.3 N
Mass of cylinder (m) = 0.82 kg
Radius of cylinder (r) = 0.045 m
Formula for torque pulling force on the cylinder is as follows.
=
Moment of inertia of the cylinder (I) is as follows.
I =
= angular acceleration of the cylinder
Hence,
Fr =
or,
=
= 124.66
Amount of line pulled is h and it is in a times of 0.2 sec.
Now, linear acceleration is calculated as follows.
a =
=
= 5.61
Now, relation between h and acceleration as follows.
h =
here, = 0
Hence, calculate the value of h as follows.
h =
=
= 0.1121 m
Thus, we can conclude that acceleration of the fishing reel is 5.61 and it will pull 5.61
line from the reel in 0.20 s.
